The Equilibrium Konstant

The Equilibrium Konstant

1. a) kc = [HCl]2 / [H2] [Cl2]

b) kc = [SO3]2 / [SO2]2 [O2]
c) kc = [NH3]2 / [N2] [H2]3
d) kc = [CO2]2 / [SO]2 [O2]
e) kc = [N2O] / [N2] [O2]1/2
f) kc = [H+] [CN-] / [HCN]
g) kc = [H+] [HSO4] / [H2SO4]
h) kc = [NO2] / [NO] [O2]
i) kc = [Pb2+] [F-]2 / [PbF2]

Guys, how do I get the subscripts and superscripts to show up?
